Two-way horizontal servo pressure machine for transmission of planet roller lead screw

Abstract

The invention discloses a two-way horizontal servo pressure machine for transmission of a planet roller lead screw. Two servo motors simultaneously drive one worm gear through two worms, a planet roller lead screw device is embedded into the worm gear, the worm gear drives a planet roller lead screw nut to rotate, the nut converts rotation into linear motion of the lead screw through a roller, dies at the two ends are driven to perform two-way stamping, the horizontal type arrangement form is adopted, a driving device is installed in a machine body, the machine body is installed in the middle of the pressure machine, the dies are symmetrically arranged on the two sides of the machine body, the structure is greatly simplified, and the structure of the whole machine is compact; the stamping efficiency is improved, energy consumption is reduced, and the service life of the motors is prolonged; loads of each worm are reduced, power of each motor is reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a servo press, in particular to a bidirectional horizontal servo press driven by a planetary roller screw. Background technique [0002] The press is an important pressure processing device in the field of material forming. It pushes the punch to move mechanically (crank, toggle or lead screw) or hydraulically (hydraulic cylinder), and completes various processes such as stamping and cutting of the blank to obtain different There are a large number of shapes and sizes of parts, among which mechanical presses are the most widely used. With the development of modern manufacturing technology, it is required that the press not only has the characteristics of high precision, high speed and large load, but also can adapt to various processing conditions and has higher flexibility. The application of AC servo motor greatly improves the working performance and process adaptability of the press, and makes the traditional pressure proce...

AI Technical Summary

Problems solved by technology

Most servo presses are generally driven by a single motor in order to reduce the control accuracy. For large tonnage, a large-power motor and a large-sized connecting rod structure are required. used together, which not only increases the structural complexity, but also increases the design and manufacturing costs

For high-speed, high-load stamping, due to the large forming force, the frequency of forward and reverse rotation of the motor is also limited to a certain extent
